Abstract
Patients with novel coronavirus pneumonia show increased thrombotic risk. Although hemostatic alterations have been described in novel coronavirus pneumonia patients, case-control studies of von Willebrand factor (VWF), factor VIII (FVIII), and a disintegrin-like and metalloprotease with thrombospondin type I motif, member 13 (ADAMTS13) are lacking. VWF, ADAMTS13, FVIII, D-dimer, C-reactive protein, and routine blood cells and chemistry were measured in 10 novel coronavirus pneumonia patients and 10 non-novel coronavirus pneumonia controls. Hemostatic factors were measured less than 48 h of hospital admission in patients without invasive ventilation. D-Dimer, C-reactive protein, and fibrinogen concentrations, high in both groups, did not differ significantly in novel coronavirus pneumonia vs. non-novel coronavirus pneumonia patients. Median VWF-antigen (324 vs. 153 IU/dl, P < 0.0001), VWF-Rco (342 vs. 133 IU/dl, P < 0.001), and FVIII-activity levels (203 vs. 123 IU/dl, P < 0.0001) were significantly higher in novel coronavirus pneumonia cases vs. controls ADAMTS13-activity was normal in both groups. Coronavirus pneumonia cases vs. non-novel coronavirus pneumonia controls showed marked VWF/FVIII elevation, suggesting specific virus-induced endothelial activation causing VWF/FVIII hypersecretion, which may represent a therapeutic target in novel coronavirus pneumonia.
